Each page of the Bitbucket Server's web interface includes a footer that is similar to the one below: 

There are two elements of this footer that can be customized:

1. The Contact Support link
2. The line that is highlighted in the screenshot above

1. Starting with Bitbucket Server version 6.2, you can customize the Contact Support link, by adding to your bitbucket.properties file a line similar to the following:
   footer.links.contact.support=https://mylink.example.com
   and restarting your Bitbucket Server (or Data Center nodes), in order to apply the change.
   For more information please refer to: Bitbucket Server config properties - Footer.
   
   
2. You can also customize the highlighted line of the footer, as needed, using the method described below.

Editing Information in the footer
